Harpoon has been pouring on Northern Avenue in the Seaport’s Marine Industrial Park since long before the neighborhood grew glass towers, and its guided tastings are the quick, low-commitment way in. In about twenty-five minutes, a staffer walks a small group through a lineup of pours — flagship IPA, UFO wheat beers, seasonals — with the stories behind them. Saturdays add a longer, fuller brewery tour for anyone who wants the whole production picture.

Afterward, the beer hall is the real draw: communal tables, a working brewery humming behind glass, and house-made pretzels that have earned a following of their own. It suits groups with mixed levels of beer nerdery, since anyone can peel off to the hall while others tour. Under-21s can come along with a parent or guardian; drinkers need a valid ID. Book online or take your chances same-day.
